I have this too....it developed out of nowhere over this last year. I don't get hives though, instead my stomach feels like its attacking itself - not fun. It usually gives me a day of puking. I was just tested for it using a blood test. I also can do cake just fine.

Awe. I had that done when I was like fifteen and I crie like a baby. I hate needles so being pricked like twenty time was a nightmare. Not to mention I was allergic to 95% of the stuff that wa tested which was fruits and veggies. Then had another done to find I'm allergic to nuts and seafood.
I wish I got those cool bracelets. Then again I don't think you'd see my arms lmao.
